Application filed June 21, 1923. Seriali No'. 646,940.

To all fw'wmit may concern:

Be it known that l, DON A. CLARK, a citieen of the United States, residing at Cleveland, in the countyy ofl Cuyahoga and State of Ohio, have invented a certain new `and useful llmprovernent in Winding' Drums, of`

which the following isa full, clear, and exact description, reference being had tothe accompanyingdrawings. I f

f lln rolling mills producing metal strips it is customary, in order to reduce `as far as possible the `amount ofspace required by.

the finished goods, to form into coilsthose strips whose thickness Adoes not prohibit. At the present time various machines are being employed to accomplish this result and these various machines are utilizing various types of winding drums'but sofar as l am aware none of the drums now inuse are satisfactory particularly because none of the drums satisfactorily grip, collapse, and o erate. My invention provides i aA drum vdiich overcomes the dilhculties heretofore existing and satisfactorily coils the strips.

lln thedrawings accompanying this speci-- fication and forming apart thereof 1 have shown, for purposes of illustration, one

physical embodiment which my inventive' concept may assume. 1n these drawings:Y e Figure 1. is a side elevation of this illustrative embodiment of my invention,

All)

Figure 5 is a section on the line 5-5 of Figure 2, while Figure 6 is a view similar to Figure 2 showing the drum in collapsed position.

Clhe drum herein disclosed ,may be suported in any suitable manner and driven y any suitable mechanism but ll prefer to support the drum on a shaft such as the shaft 12 herein illustrated and to operate this shaft 12 by means of the mechanism disclosed in my co-pending application executed September 19, 1924, fi ed September 22, 1924, bearing Serial Number 739,148, and entitled Drumming mechanism. The drum herein shown comprises a plurality of face sections 11, herem shown as three in number, each supported m the means of-a pair of links 13 and `aan 12 :ig

at their inner endsy upon pivot 14. pivote rods 15 and 16 carried by rings 17 keyed tov the shaft 12 and pivoted atther outer ends A upon pivot rods18 and 19gcarried by ribs 20 projectinglinwardly from each face section 1.1. Because of the pivotal support of the sections 11 from the shaft 12 it will be obvious ythat these sections may be moved relative to the shaft12 and it will further be.robvious that with the sections initially in the position shown in Figure 2 with the links 13v and 14 substantially radial any such movement of the sections 11 relative to the shaft 12, while it may result .in moving some part of the sections further from the .shaft 12 during the initial steps of the relatlve movement, will nevertheless at all times.

result in the section as 'a whole moving closer to the shaft 12. 1n the drum herein shown ll have, however, so proportioned the links`13. and 14 that upon movement ofthe sections 11 relative to the shaft 12 each Section 11 will partake of a substantially translatory'- movement in which the entire face of the section will at theend of the movement be substantially paralleltothe position which it previously occupied and accordingly in the drum herein shown such movement of the `sections 11 relative to the shaft 12 roduces a substantially uniform decrease 1n diameter of the drum. Cf course this decrease in diameter of the drum necessal-'ily decreases the circumference thereof and in orderito provide for this decrease each of the sections 11 ismade sonnewhat shorter than its -proportion of the en tire lcircumference so that with the drum expanded gaps 21 exist between the adjac ont sections. p v

lln a drum of this type it is desirablethat the sections 11 move simultaneously between expanded and colla sed position and' derive their collapsing an expanding motion from t a single operating instrumentality. Accord-- ingly, in the drum herein illustrated l have extended the pivot rods 18 and 19 `through apertures in a pair of end lates 22 and 23 looselyYV mounted upon the s aft 12 whereby movement of lany one of the sections 11 must act, through its Apivot rods 18 and 19, the plates 22 and 23, and the pivot rods 18 and 19'` of theother sections, to impart to the other sections a simultaneous movent and lldll whereby movement of either of the plates 22 or 23 will act through all of the pivot rods l' 18 and 19 to impart to all of the sections simultaneous collapsing or expanding movement.

n In the'kdrumherein shown means are also rovided for gripping the end of the strip to be coiled and in addition this gripping means is so arranged and connected as to be automatically operated upon collapse or expansion of the drum. The particular gripping means herein illustrated comprises dogs 24 pivoted upon pivot rods 25 carrled by the kribs 20 of the face plates 11 and each providedl with a taily 26 arranged to be engaged by a bar 27 mounted in the-rings 17 carried by the main shaft 12. The-location of the pivot rods 25 and the bars 27 and the contour of the dogs 24 are so corelated that movement of the sections 11 relative to the shaft 12 to move the sections from collapsed to expanded position will swing the dogs 24 about their plvot rods 25 to Acause each grippingfacve 28 to clamp tightly between itself andthe gripping face 29 of that particular face section 11 any strip 30 which 'has been inserted between the faces 28 and 29 and similarly so that collapsing1 movement of the' sections 11 will permit t e dogs 24 to swing in the reverse dlrection to release any strip which has been clamped. In the drum herein illustrated I have shown the pivot rods 25 carrying thesek dogs 24 as also extending lthrough the side plates 22 and`23 and under certain circumstances, particularly in large machines, I find this desirable, but it will be understood lthat while I have shown' the pivot rods 18 and 19 and 23 as all extending through the side plates 22 and 23 under many circumstances it is only necessary that one rod from each face plate section 11 extend through these side plates 23 and 22 and that under some conditions it may be sufficient lto merely extend this rod or rods cured to the end plate 22, freely rotatable with it upon the shaft 12,-and meshing with a pinion 32 carried by a shaft 33 which car,- ries. on its other end a high inertia fly-wheel 34 and is supported in a bearing 35 shown assupported by the main frame of the mechanism utilized for rotating the winding drum. The inertia of the fly-wheel 34 and its connection to the end plate 22 are such that it will tend to cause the end plate 22,

.- tion as rotation and with it the sections 11, to lag behind the shaft 12 bothin starting and stopping and the collapsing and expanding movement of these sections .11 is in such direction (as shown in Figure 6) that this lag of the end plate 22 and sections 11 will cause the sections 11 to expand as rotation of the shaft 12 is initiated and to collapse as rotation of the shaft 12 is terminated. In addition, because of their inter-relation with the sections 11 and the collapsing and expanding movement thereof, this lag of the end plates 22 and sections 11 will simultaneously automatically cause the dogs 24 to swing into gripping position as rotation of the shaft 12 bcgins and to swing away from gripping posiof the shaft 12 is terminated.

In operating the sections 11 and the dogs 24 automatically upon be 'nning and terminating the rotation of t e shaft 12 it is probably necessary that the sections and dogs operate easilyv and it is therefore at least desirable that in the expanding movement of the sections the links 13 and 14 shall not move beyond the radial position or in fact even to the radial position and I therefore proportionthe parts in such manner that the gripping faces 28 o f the dogs 24 will engage' the cooperating gripping faces 29 of the sections 11 before the links 13 and 14 have quite reached radial position and of course with the parts so designed the gripping face 28 of the particular dog involved will engage the stock 30 while the links 13 and 14 are still a somewhat greater distance from radial. In order to clearly indicate this feature I have shown in Figure 3 the relative position of the shaft 12 and the link `13 and have indicated by the letter A the angle between the axis of the link 13 and a radial line through the shaft 12 and pivot rod 15.

With the parts arranged in this manner, elimination of tension upon the strip permits the strip to shift upon the drum 11 in such manner as to act to collapse the drum. This reduction of tension may occur normally by the emergence of the end of the strip 11 from the mill or` abnormally through various causes such as the stoppage of the drum driving mechanism, abnormal operation of the mill, or abnormal condition of the strip. Inasmuch as the tension on the strip is the onl force acting to maintain the drum expande after the flywheel 34 has 'reached operating speed I find it desirable to equip the herein described mechanism with a means adapted to either continually or momentarily impart a drum expanding impulse suicient to maintain the drum expanded during such abnormal conditions and I have therefore shown the within described mechanism as provided with a brake shoe 36 arranged to engage the iiv-wheel 34 and support by a resilient arm 372' which is Lerares a carried by aboss 38 rising fromthe main frame and which is of suicient strength to impart the desired pressure t the brake shoe 36.-

Under'certain conditions and with certan relations of the partsthe drum collapsing action of ,the strip, as the` end of" the strip emerges fromthe mill,-may be' of suiiicient strength to collapse the drum 11 without assistance from the lfly-wheel 34 andin such case it is obvious that the brake shoe 36 may be maintained in constant engagement `with the fly-wheel 34. However, even with the partsso proportioned, I prefer to construct this brake mechanism Vin such manner `that the brake shoe 36 may be' readily retracted from its engagementwith the ily-'wheel34 and l have therefore providedthe mechanism herein disclosed `-witha'cam member 39 pivoted in a clevis 40 rising from the main frame of the machine andarranged when actuated by a suitable'handle 41 kto engage a shoulder 42 on the arm 371to move the arm 37 suciently to remove the brake shoe 36 from its engagement with the iiy-'wheel 34.

-Under certain circumstances it may be desirable to `maintain thebrake shoe 36 in entire operation of the drumbut remove the brake shoe 36 from engagement withthe flywheel 34 as the rotation of the drum is terminated and in such caseI may readily interconnect the. handle 41 with the means which control the rotationof the drum.

f llt u will be obvious to those skilled in the art that the winding drum herein shownis operative for the purposes forwhich it has been designed andr in addition obvlates the diculties heretofore existing in drums constructed for the uses for which Ithis drum is particularly adapted, and that the particular construction herein disclosed may be variously vmodified and altered without sacrificing the advantages or departing from the essentials of my inventive concept. Furthermore, it will be obvious to those skilled in `various arts that the drum herein shown, or somev modification thereof which is within my inventive concept, may be utilized for variouspurposes other than the one herein specically considered and both within the art herein considered and within other arts. lt'will therefore be obvious that my invention is not limited to the specific physical embodiment herein disclosed and that this particular disclosure is illustrative on Y claim: v .y
